This award would continue the operations of the Magnetometer Array for Cusp and Cleft Studies (MACCS) network combined with the dissemination of its data and the scientific analysis of MACCS data in collaboration with other ground-based and space-based research teams. MACCS is a longitudinal array of high latitude fluxgate magnetometers covering the Eastern Canadian Arctic at high latitudes(75-85N), providing continuity of spatial coverage between existing Canadian and Greenland arrays. MACCS has contributed to the study of ULF waves and transients at these extreme latitudes as well as large cooperative studies of magnetosphere-ionosphere coupling, ionospheric convection, and magnetic storm and substorm processes. The combination of the location of several MACCS stations under the field of view of the SuperDARN / PolarDARN radar network, their proximity to the field of view of the AMISR radar system at Resolute Bay, Canada, and the nominal "conjugacy" of four MACCS stations with U. S. Antarctic stations as well as the recent addition of dual high-sampling-rate GPS TEC receivers makes possible additional comparative studies that would be quite rich in possible transformative outcomes. Each MACCS site transmits data in near real time (two through Iridium, six through the local wireless internet. The MACCS array has provided ground-based magnetic field observations that will continue to play a fundamental role in magnetospheric and ionospheric research and will continue to provide critical data for studies of various geospace phenomena including solar wind-magnetosphere and magnetosphere-ionosphere interactions, the dynamics of the high latitude polar cap regions of the magnetosphere, and geomagnetic storms and substorms. The scientific analysis of MACCS data would focus on the topics such as the detailed studies of high-latitude ULF waves, using multi-instrument ground-based and satellite data from the Van Allen Probes and SWARM and studies of the role of ULF waves in energizing or depleting radiation belt electrons during magnetic storms. Theoretical studies and modeling studies (using the Space Weather Modeling Framework) of the excitation and propagation of ULF waves through the global magnetosphere-ionosphere system, and exploring the physical mechanisms involved would be particular aspects of the science issues covered in this award.

该奖项将继续开展尖端和裂隙研究磁强计阵列(MACCS)网络的业务，并与其他陆基和天基研究小组协作，传播其数据和对MACCS数据进行科学分析。MACCS是一个高纬度磁通门磁力仪纵向阵列，覆盖加拿大东部高纬度(75-85 N)的北极地区，在现有的加拿大和格陵兰阵列之间提供连续的空间覆盖。MACCS对这些极端纬度的超低频波和瞬变的研究以及对磁层-电离层耦合、电离层对流以及磁暴和亚暴过程的大型合作研究作出了贡献。几个MACCS站在SuperDARN/PolarDARN雷达网视野下的位置，它们靠近加拿大索鲁特湾的阿米西尔雷达系统的视野，四个MACCS站与美国南极站名义上的“共轭”，以及最近增加的两个高采样率GPS TEC接收器，使得额外的比较研究成为可能，这将是非常丰富的可能的变革性结果。每个MACCS站点都近乎实时地传输数据(2个通过Iridium，6个通过本地无线互联网。MACCS阵列提供了地面磁场观测，将继续在磁层和电离层研究中发挥基本作用，并将继续为研究各种地球空间现象提供关键数据，包括太阳风-磁层和磁层-电离层相互作用、磁层高纬度极帽区域的动力学以及地磁暴和亚暴。对MACCS数据的科学分析将侧重于以下专题：利用来自Van Allen探测器和群的多台仪器的地面和卫星数据详细研究高纬度极低频电波，以及研究磁暴期间极低频电波在激发或耗尽辐射带电子方面的作用。对全球磁层-电离层系统中的超低频波的激发和传播进行理论研究和建模研究(使用空间天气模型框架)，以及探索所涉及的物理机制，将是本奖项所涉科学问题的具体方面。
